EUROPEAN AND MEDITERRANEAN PLANT PROTECTION ORGANIZATION ORGANISATION EUROPEENNE ET MEDITERRANEENNE POUR LA PROTECTION DES PLANTES 20-25860 Pest Risk Analysis for Gymnandrosoma aurantianum (Lepidoptera: Tortricidae), citrus fruit borer, macadamia fruit borer H. Blanco-Metzler. Adults of G. aurantianum, Costa Rica. September 2020 EPPO 21 Boulevard Richard Lenoir, 75011 Paris www.eppo.int [email protected] The risk assessment follows EPPO standard PM 5/5(1) Decision-Support Scheme for an Express Pest Risk Analysis (available at http://archives.eppo.int/EPPOStandards/pra.htm), as recommended by the Panel on Phytosanitary Measures. Pest risk management (detailed in Annex 1) was conducted according to the EPPO Decision-support scheme for quarantine pests PM 5/3(5). The risk assessment uses the terminology defined in ISPM 5 Glossary of Phytosanitary Terms (available at https://www.ippc.int/index.php).

Available at https://gd.eppo.int/taxon/ECDYAU/documents 1 Based on this PRA, Gymnandrosoma aurantianum was added to the EPPO A1 List of pests recommended for regulation as quarantine pests in 2020. Measures for Citrus fruits are recommended. Pest Risk Analysis for Gymnandrosoma aurantianum (Lepidoptera: Tortricidae) PRA area: EPPO region Prepared by: Expert Working Group (EWG) on Gymnandrosoma aurantianum Date: 18-21 November 2019. Further reviewed and amended by EPPO core members and Panel on Phytosanitary Measures (see below).

Blanco-Metzler (Universidad de Costa Rica, Costa Rica), R. Parra (University of São Paulo, Brazil), L. Torta (University of Palermo, Italy), N. Üstün (Ministry of Agriculture and Forestry, Turkey). The first draft of the PRA was prepared by the EPPO Secretariat. Ratings of likelihoods and levels of uncertainties were made during the meeting. These ratings are based on evidence provided in the PRA and on discussions in the group. Each EWG member provided a rating and a level of uncertainty anonymously and proposals were then discussed together in order to reach a final decision. Following the EWG, the PRA was further reviewed by the following core members: N. Avendaño Garcia, J.M. Guitian Castrillon, A. Sağlam, E. Guachet, F. Petter, M. Suffert, D.J. Van Der Gaag. The PRA, in particular the section on risk management, was reviewed and amended by the EPPO Panel on Phytosanitary Measures on 2019-10-22/24 and 2020-03-24/26. The EPPO Working Party on Phytosanitary Regulations and Council agreed that Gymnandrosoma aurantianum should be added to the A1 List of pests recommended for regulation as quarantine pests in 2020. 2 CONTENTS Stage 1.
